The Best Photos from Vogue's Pre-Met Gala Pajama Party

As you're surely aware, tonight is the 2015 edition of Vogue's biggest soiree of the year: The Met Gala. This year's event celebrates the opening night of the Metropolitan Museum of Art's current Costume Institute exhibit: "China: Through the Looking Glass."

To gear up for the big night, Vogue hosted a pre-party Saturday night in New York's Chinatown neighbourhood. Guests--who included some of the fashion set's biggest names like Alexa Chung, Bella Hadid, André Leon Talley, and more--were encouraged to wear traditional Chinese garb as an homage to the Costume Institute's theme. Oh, with one more twist: Everyone was asked to wear pajamas.
